Resource Provisioning Based on Lease Preemption in InterGrid
Resource provisioning is one of the main challenges in resource sharing environments such as InterGrid. Recently, many resource management systems in resource sharing environments use lease abstraction and virtual machines for provisioning. In resource sharing environments resource providers serve requests from external (grid) users along with their own local users. The problem arises when there are not sufficient resources for local users, which have higher priority than grid users, and need resources urgently. This problem could be solved by preempting leases from grid users and allocating them to the local users. However, preempting leases entails determining which lease(s) are better choices to be preempted and what should be done with the preempted leases.
